Tire tread



FIG. 1 is a perspective view of a tire tread showing my new design, it being understood that a tread pattern is repeated over the outer circumference and shoulder of a tire, the opposite side perspective view being identical thereto; and,

FIG. 2 is an enlarged fragmentary front elevation view of the tread pattern of FIG. 1 showing my new tread pattern for the tire tread.

The broken line disclosure of the tire sidewall and inner bead is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
